(2) Dynamic Convergence Adjustment Preparation: � Before starting this adjustment, adjust the horizontal static � convergence and the vertical static convergence Set the PICTURE and BRIGHTNESS to normal.
1. Adjust TLH. (TLH correction piece) 1 Receive the dot/hatch pattern signal and adjust picture quality by the menu. 2 Correct horizontal mis-convergence of red and blue of both sides on the X axis. When red is outside insert BMC magnet to right side (THL+)
